摘要

本研究开发了含有微二硫化钼（MoS2）添加剂的棕榈油基润滑脂。为研究添加剂在改善润滑脂性能方面的作用，使用不同浓度的 MoS2 制备了这种润滑脂。进行了四球摩擦学试验，以研究钢球的表面形态、磨损深度和体积损失。结果表明，与纯棕榈油脂相比，MoS2 添加剂降低了摩擦系数和磨损痕直径。0.5 wt.%的值被认为是最佳值，反映了润滑脂的最佳性能，即摩擦系数、磨损直径、磨损深度和体积损失都较低。元素分析表明，MoS2 添加剂沉积在磨损轨道上，改善了表面保护。因此，这种添加剂在改进棕榈油基润滑脂方面具有良好的潜力。

Anti-friction and Wear Resistance Performance of Palm Olein Grease with Molybdenum Disulfide Additive

In this study, palm olein-based grease with a micro-molybdenum disulfide (MoS2) additive has been developed. The grease was prepared using various MoS2 concentrations to investigate the role of additives in improving grease performance. A four-ball tribological test was conducted to investigate the surface morphology, wear depth, and volume loss of the steel ball. The results indicated that the MoS2 additive reduced the coefficient of friction and wear scar diameter compared to pure palm olein grease. The value of 0.5 wt.% was considered the optimum value, reflecting the best grease performance indicated by low friction coefficient, wear diameter, wear depth, and volume loss. Elemental analysis revealed that the MoS2 additive was deposited onto the wear tracks, improving the surface protection. Thus, this additive was found to have a good potential for improving palm olein-based grease.
